Very slow comcast internet please help!

[sarah85]

I have been having problems on and off with my internet for 2 years. I've had about 10 techs come out. The last time they came out i told them my upstream powel level was low and they fixed that. The other 9 times they came out they pretty much told me i was lying and my internet was perfect . As of right now I'm getting about 1mb down. The internet works great for a few days then back to the problems.

Any help of what might be causing my problem would be great. I don't believe it is my modem since this is my 4th one in two years. Thanks!
